North Korean scientists have invented a hangover-free alcohol, according to the Pyongyang Times.
The state newspaper says the "suave" liquor will spare you wincing when you wake, despite boasting 30%-40% alcohol.
The brew is reportedly made from a type of indigenous ginseng called insam and glutinous rice, and cultivated by an organic farming method.
The product apparently "exudes national flavour", without dampening your national fervour the following morning.

Thus comprising the two national ideals of Communism:
1) That anything they think of is more "advanced" and "scientific" than the rest of the Free World, whether or not they actually have any grasp of 21st-cty. science or not,
and
2) Providing the main wish of the people, namely to spend most of their free time drinking themselves into stupors because they can't put up with their daily life, but with the State trying to find an option with which they can still go back to work at the factory on Monday morning.

(And Russia's already got thirty years on NK for being able to drink any other ComBloc country under the table...)
